Filtering Results

Parse Extracted Data

# Extract only passwords
jq '.[] | select(.password) | {account, password}' keychain.json

# Find API keys
jq '.[] | select(.label | contains("api")) | {label, value}' keychain.json

# Extract GitHub tokens
jq '.[] | select(.label | contains("github")) | .password' keychain.json

# SSH keys only
jq '.[] | select(.type == "ssh") | {label, key}' keychain.json

Security Implications

  • Requires code execution access on macOS
  • Bypasses some macOS security prompts
  • Extracts plaintext credentials from keychain
  • Accesses browser stored passwords
  • Can harvest SSH keys and API credentials
  • Enables mass credential theft

Mitigation Strategies

  • Use Secure Enclave for credential storage
  • Disable automatic keychain unlock
  • Enable audit logging for keychain access
  • Monitor for suspicious process execution
  • Implement strong user authentication
  • Enable SIP (System Integrity Protection)
  • Keep macOS updated
  • Use separate keychains for sensitive credentials
